FOUNTAIN-SPITTOON.

SPECIFICATION forming part of Letters Patent No. 703,221, dated June 24,1902.

Application filed June 20,1901.

To ctZZ whom it may concern.-

Be it known that I, WILLIS EDW. ALLEN, a citizen of the UnitedStates,residing at Baltimore, in the State of Maryland, have inven ted certainnew and useful Improvements in Fountain-Spittoons, of which thefollowing is a specification.

This invention relates to spittoons, and particularly to that class fordentists use called fountain spittoons, which are continuously flushedby a stream or streams of water flowing therethrough.

The object of the invention is to provide an improved spittoon of thischaracter whose construction and arrangement of parts enable a thoroughcleansing or flushing of the bowl to be quickly effected and in whichall blood, cotton, or similar unsightly objects will be quickly washedout of the sight of the person being operated upon.

The invention consists in certain constructions, arrangements, andcombinations of the parts hereinafter fully described and claimed,reference being had to the accompanying drawings, in which- Figure l isa vertical transverse section of a fountain-spittoon, illustrating oneform of the invention. Fig. 2 is a horizontal section thereof, takenapproximately on the line 2 2 of Fig. 1. Fig. 3 is a detail top planview of the rotating disk adapted to throw by con trifugal action theblood, cotton, or the like out toward its edge and down into the bowl.Fig. 4 is a vertical transverse section of a fountain-spittoon,illustrating another form of the invention. Fig. 5 is a detail top planView of the rotating disk of this form of the invention. Fig. 6 is anenlarged detail side view of the rotating support for said disk. Fig. 7is an enlarged detail vertical section of a trap for the centraldischarge-opening of said disk.

Referring to the drawings, Fig. 1, the letter a designates the bowl ofthe improved fountain-spittoon, which bowl may be composed of glass ormetal and which is provided at its bottom with a tubular extension I),through which the water may discharge into a waste-pipe c. The said bowla. is also provided near its top with an outward circular flanged,wl1ich curls upwardly and at its upper Serial No. 65.252. (N0 model.)

edge inwardly, whereby to form near the top of the bowl an approximatelyV-shaped circular trough e.

Around the inside of the circular rim edge of the bowl a is secured amain spray device f, which in this instance is a ring provided with twoseries of jets g h, the jets of one series 9 opening toward the bottomof the trough e and the jets of the other series h opening inwardly anddownwardly and in a tangentialdirection fora purpose hereinafterdescribed.

The letter t designates the main water-feed pipe, which is suitablyclamped to the bowl and opens at its upper endinto the main sprayrin gf. A branch feed-pipe j is secured to the main feed-pipe and is providedwith one or more tubular arms 70, which extend upwardly on the inside ofthe bowl a near the center of the same, and a horizontal auxiliary spraydevice or ring Z is secured to the top of said arms and is provided witha series of upwardly-opening jets m, as best seen in Fig. 2. A cook oris connected with the branch feedpipe j, so that the flow of watertherethrough may be diminished below the flow of Water through the mainfeed-pipe i.

Within the bottom of the bowl (1 is secured an upwardly-extending spider0, provided at its upper end with a cone-bearing p, and a disk q (shownin detail in Fig. 3) is mounted to rotate about its center on saidbearing and extends over the auxiliary spray-ring Z, as indicated inFigs. 1 and 2. The marginal edge of said disk is close to, but spacedfrom, the side wall of the bowl 0. just below the inner upper edge ofthe V-shaped trough e, whereby a passage 1" is formed, and said disk isprovided directly over the auxiliary spray-ring t with segmental slots3, through which the water issuing out of said spray-ring may pass ontothe upper surface .of the disk.

In order to catch. the cotton, gold, or other substances washed into thebowl, there has been provided an annular pan t, intended to rest withoutpermanent attachment in the bottom of the bowl or and provided with anupwardly-curled inner edge to, having apertures o to let water through.All unsightly objects injected into the bowl will be washed into thesaid pan, and the latter may be lifted out of the bowl and cleansed.Also if the disk (1 should be made of glass the curled-up edge u of thepan will hide the said objects.

In practice water issuing out of the tangential jets h of the mainspray-ring f will strike the upper surface of the disk q in such adirection as to cause it to rotate, the water issuing out of the otherseries of jets 9 will fill the trough e and overflow, so that a thinsheet of water will continuously flow down the inner surface of thebowl, and the water issuing out of the auxiliary spray-ring} will flowthrough the slots 8 over the outer surface of the rotating disk q andwill also, on account of striking the webs which are located betweensaid slots, be deflected over the under surface of the disk. The saiddisk q, as indicated in Fig.1, is curved in cross-section, and its uppersurface is for the most part convex. Hence as the disk rotates thecentrifugal action will cause all unsightly objects injected onto thedisk to be quickly thrown out into the passage r, and they will thenpass downwardly underneath the disk and out of sight.

In that form of the invention illustrated in Figs. 4 to 7, inclusive,the bowl a is provided with an outward flange (1, having a morepronounced curl than the flange of the first-describedconstruction,whereby to form a larger V-shaped trough 6'. Around theinside of the rim edge of the bowl is secured a spray device in the formof a ring f, which is provided with two series of jets g h, disposedlike the series of jets g and h, and to said ring is connected thewater-feed pipe 11. In the tubular discharge 5 of the bowl a is secureda web-plate in which is rigidly held a vertical spindle 19', having acone-shaped upper end. A cup-shaped disk-support w is provided with asocket wherebyit is mounted to rotate on said spindle end and is alsoprovided with a depending skirt as, surrounding said spindle end, sothat water will not be liable to reach the cone-bearing, and the up- 1per end of said disk-support is provided with pression q (1 around thecenter.

a plurality of vertical slots 3 as shown best in Fig. 6. Supported onthe upper rim of the cup-shaped rotary disk-support w is a disk q,having a depressed central portion (1 with a discharge opening .9coincident with said disk-support, and also having a downwardlycurvedouter edge spaced from the bowl-wall, so as to form a passage 1", and aperforated cup-trap z fits down inside of said dischargeopening, asshown inv Fig. 4.. A perforated pan 1) rests unattached in the bottom ofthe bowl a. When the tangential jets h strike the disk q, the latterwill rotate and the water will wash any object injected onto the diskeither down the passage 1" or through the central discharge-opening s.

In both forms of the invention illustrated in the accompanying drawingsit will be observed that the disks q and q both have a de- In the diskillustrated in Fig. 1 the depression g is annular and surrounds a peakat the center of the disk, and in the disk illustrated in Fig. 4 thesaid depression g surrounds the central dischargeopening 8. In eithercase when the water is sprayed tangentially on the upper surface of thedisk the said depression will contain a whirling sheet of water. In theconstruction of Fig. 1 the depression will overflow to the other partsof the disk. In the construction of Fig. 4 it will not likely overflow,but will pass out through the central discharge-opening s.

It is to be understood that the invention is not confined to a spraydevice in the form of a ring, as two distinct nozzles, one pointinginward and tangentially and the other pointing outward toward thebowl-wall, may be employed, and changes in the detail construction ofthe parts may be made without departing from the scope of the inventionas defined in the appended claims.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
